Wilwood Front Black Dynalite Brake Kit for Ford Mustang II/Pinto and Mercury Bobcat (1974–1980), 12.19-Inch Plain

Black Dynalite calipers and plain 12.19-inch vented rotors form this Wilwood front hub conversion. The bracket package is for the original disc spindle used by the specified Mustang II, Pinto and Bobcat applications. Replacement five-lug hubs are included, distinguishing the assembly from a four-lug service replacement. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Confirm the original disc-brake spindle, not the earlier drum spindle, for the exact vehicle row. DS614 identifies the five-lug configuration and supported bolt patterns. The stated OE wheel offset is unchanged, but spoke clearance still requires the actual wheel drawing. Select hydraulic hoses separately and check the installed master-cylinder pushrod arrangement if hydraulic components are changed.

Match the individual model, year, submodel and brake configuration in the fitment table below.
